Good Idea.
I personally do not understand what parts of adulthood were kept and what parts were gone, as behavioral traits vary. Besides that, if you slowed down the pace of the article (which I personally believe goes too fast) and removed the collapsibles (which could be put plainly and still work), it would be a-ok.

Okay, here we go. Got a PM about this. Since there's a lot of stuff still backlogged in the forums, this is a quick read. Here are my thoughts:

Containment procedures are messy and kind of silly-looking. Why does this thing necessitate a perfectly-cubic containment unit taller than a 3-story building? Capitalize Level-3 and give it a hyphen, "any time" is two words, and I really don't think an O5 Councilmember would bother commenting on this thing's file or even be involved. The Council has more important things to weigh in on. Furthermore, all the freaking out and the "make it Keter, terminate the sub-designations" on the part of the Site Director seems like the author trying really hard to push for how dangerous this thing is. It comes off as excessive.

The censoring is a little sloppy:

Note that no subject has been successfully removed from SCP-XXXX during this process, and all attempts made have resulted in [TOTALLY SICK AWESOME DANCE PARTIES].

This is supported by MRI scans that revealed [UNICORN-SHAPED TUMORS] which are greatly depleted by the end of SCP-XXXX's nine (9) month inactive period.

I recommend reading over this guide on interesting expungment for some tips. Also, we've already got a lot of body horror and gore on the site already, so having this kind of expungment just kind of feels cheap at this point. The snarky note from Doctor Flynn just makes me kind of roll my eyes and take the article a lot less seriously.

Overall all I'm getting from this is basically "blob monster with a lot of random behaviors and gross digestive properties that hunts sexually mature humans and only humans for… some reason". It sort of feels like a mishmash of existing SCP objects and some generic D&D monsters.

Did you get the concept checked in the Ideas and Brainstorming forum before starting the draft? It feels kind of like the standard monster for the sake of monster stuff that we see get deleted off the site every week.

Thank you so much for your feedback! After relooking at it through someone else's eyes… You're right. My idea and format needs some serious reworking and I appreciate you giving me a fresh perspective so I didn't end up wasting the site's space with something people have seen before.

While I have every intention of going to the Brainstorming forum and "return to the drawing board" as it were, I was wondering if you could give me a rough idea of what the site is looking for as of right now.

I looked over some of the more popular recent SCPs, and many of them seem to play with the format.

While I do understand that an idea can't survive on playing with the format alone, would you say I'd have a better chance of 'hooking' people with a varied format, rather than trying to sell the idea in the more 'vanilla' writing format?

I would love to hear more from you on this when you get a chance, and thank you so much once again for your feedback.

The most I can really say is "well-written, unpredictable stuff". With over 3500 articles on the site, and much, much more material that gets deleted every day, there's a lot that the community has already seen. New concepts and quirky storytelling work well, since novelty is always appreciated here.

That's why Ideas and Brainstorming is helpful; one of the best things to ask at that stage is "has this been done before?" And then the follow-up, if the answer is yes (typically, it is) is "how can I make my thing different enough to stand out?"

Depends on the format, and the reader. Some people really don't like format screws and will downvote for those if they don't seem to serve a narrative purpose.
